F3 Pending Deactivation
State after deactivation from the S/T interface by info 0. Note that no activation from the
terminal side is possible starting from this state. A ’DI’ command has to be issued to enter
the state ’Deactivated State’.
F3 Deactivated State
The S/T interface is deactivated and the clocks are deactivated 500 µs after entering this
state and receiving info 0 if the CFS bit of the IPAC-X Configuration Register is set to “0“.
Activation is possible from the S/T interface and from the IOM-2 interface. The bit
TR_CMD.PD is set and the analog part is powered down.
F3 Power Up
The S/T interface is deactivated (info 0 on the line) and the clocks are running.
